I am installing a different tripod for my satellite antennas. 25 feet tall with 5 feet between the legs at the base. It will be set up to be tipped over for antenna access. Does anyone have any experience with a similar system? I have a few ideas already from my elmer J oe-K0VTY. You can neve r have too much information. I have a welder, concrete mixer and strong grandsons for moving things around. Pictures available upon request. Any ideas are appreciated.

Hi Bob
Just go on my web page www.qsl.net/ve2dwe i have 3 4X4 wood post. The 3 bottom post are drilled to pass a metal round bolt making the center pole moving from flat to ground to vertical. When i want to secure the middle post i drilled a hole through the 3 top pole section and i insert another long bolt through them with two nuts making a very strong structure. I even attached a DME tower section to the middle post making any antenna adjustment available at any convenient height.
To move this middle section i'm using a double pulley system and i included a manual winch to have more control on the middle section movement.
This system was holding a 7.5 foot dish (Old TVRO) until the metal mast inside the DME broke in a winter ice storm.
